An apparatus for helping locate an item of interest in or near a building comprises an indicator and a body with a pair of pincers adapted to operate in opposition to grasp or be placed on or near the item of interest. The body houses a radiofrequency (RF) receiver configured to receive RF signals transmitted by an RF transmitter, and a processor in communication with the RF receiver and the indicator. The processor is configured to acquire information from the RF signals that are received by the RF receiver and to turn on the indicator in response to the information acquired from the RF signals.
